BEV battery technologies changing fast

GM's new battery news is exciting

Great that they went outside the box in form factor, but the risk as always...will this become a commodity level form factor...AKA Beta vs VHS

One of the why's OEM'S wait to let the scouts
to the arrows and financial risks. Though if successful, the risk becomes huge returns

Here is an exciting one https://news.samsung.com/global/samsung-presents-groundbreaking-all-solid-state-battery-technology-t...

My favorite, saline batteries, has stalled on their electrode tech

Hope Tusk's giga factories can be retooled quickly...and if he has a retrofit plan.

Dang....I was set to purchase an EV next year. Because of this rapidly changing battery world, I might have to wait a couple of years. Can you imagine not needing a charge on an EV for over 600 miles? I wonder if the charging world will be able to keep up with the battery technology advancement rates? I might have to add more solar on my home because of this too.

Will not take additional power unless you drive more miles. Just as a truck with the optional larger tank does not use more fuel unless you drive more miles. You just fill less often.

This is not anywhere near enough - in my opinion. If one was to "top up" their EV battery once a day every day - just to feel good with regards to always leaving home with their EV battery at the 100% charge level (like we do with our smartphones) - then the EV battery would only be good for a little over 3 years (3 X 365 days = 1095 days = 1095 recharge cycles).

A charge cycle life of 3000 or more cycles would be more like it ... to go along with the estimated 800km EV range.

Charge cycle is based on 100% discharge equivalent. So the 400 mile battery goes 400,000 miles before replacement. Most vehicles are long done before that mark.

GM has an eight year warranty on the battery. So I am not sure what constitutes a cycle, but I cannot believe that you can kill the battery in 3 years.

But I will see, since I just got one and will have it for 36 months.

The future will be interesting!
